The soggy month, which will also go down as our dampest since at least December 2010, leapfrogged into first place on the list of all-time wettest Marches, surpassing the previous mark of 8.40 inches from March 1950 while also bumping March 1997 (8.15 inches) down to third. Seattle weather records date back to 1891, when observations were first taken at the Federal Building in downtown Seattle. Since 1945, Sea-Tac Airport has served as the official weather-reporting site for the city.
